Evaluation of Post Impact Control Function with Steering and Braking Superposition in High-fidelity Driving Simulator

Paper in proceeding, 2015

This paper evaluates the effectiveness of an active chassis control function after an initial light impact. The experiment was designed in a high-fidelity driving simulator with motion platform that is adapted to mimic a real-world crash. The post-impact control function here superimposes individual-wheel brake and steering wheel torque in order to minimize the vehicle maximum lateral deviation from its original traveling lane. It is found out that drivers with the function intervention has smaller lateral deviation after the disturbance from an initial impact, and thus less risk of leaving the road which may cause a secondary impact. The driver reaction with and without the function is also found to be different in terms of both braking the steering behaviours.
